The CHOPIN Technologies Alveolab® is an easy to use, versatile analyzer that provides automated testing of flour and dough characteristics. The instrument is self-controlled with its own cooling system, automatic water injection, and automatic positioning, crushing and blowing of the dough patties. The Alveolab® is more adaptable with a wider range of protocols and meets international standards.

How It Works
Focus on the Analysis, Not the Training
The Alveograph test consists of producing a test piece of dough, which, under air pressure, turns into a bubble. This process reproduces the deformation of the dough when subjected to carbon dioxide during fermentation.
The Alveolab® does not require extensive training, allowing staff to begin using the analyzer right away. In addition, new employees can be trained quickly instead of spending more time learning the system. With the labor shortages facing the industry and employee turnover, being able to train employees in less time means you can continue analysis without large gaps in your schedule. The Alveolab® also allows you to conduct multiple tests simultaneously, which saves time and cost. The ease of use and versatility results in ROI being realized quickly.
The Test Involves Four Main Steps
- Mixing flour and salted water
- Preparing five calibrated pieces of dough
- Putting these pieces of dough to rest
- Automatically inflating each piece of dough until the resulting bubble bursts
Automated & Fully Controlled Test Conditions
- Automatic regulation of temperature and hygrometry, meaning the results are independent of environmental conditions.
- The positioning and the inflation of the dough pieces are automated and carried out in a temperature and humidity-controlled compartment.
- The inverted bubble is more spherical and closer to the ideal conditions of the test.
- Results are provided in graphical and table format to quickly assess the dough behavior.
Dough Hydration
- At the beginning of the test, water is added automatically and very precisely.
- The temperature of the water tank is regulated.
Integrated Cooling System
- Cooling is assured by an integrated system (Peltier effect). Therefore, there is no need to connect the equipment to a cooling water system.
Adapted Hydration Test
- The Alveolab, equipped with its “Adapted Hydration Kit,” allows testing of flours based on their actual absorption capacities. The protocol requires an initial Consistograph test, which lasts only 5 minutes, to determine the flour's water absorption capacity. After the Consistograph test, the adapted hydration Alveograph test proceeds as normal. This process provides users with a better understanding of their flour’s functionality using a water level more consistent with production conditions, especially for hard wheat flour types.
Extrusion and Cutting of Dough Pieces
- Resting plates have a high-resistance anti-adhesive coating to facilitate the preparation of dough pieces.
- Dough cutter is semi-automatic and very easy to use.
Whole Wheat Test
A unique feature of the Alveolab® is its ability to analyze whole wheat flour. The Alveolab® is the only Alveograph that can measure whole wheat flour. Whole wheat flour has a high hydration capacity, longer development times, and is more fragile due to large particles, which makes it more challenging to test. With a new testing protocol, these challenges have been removed and bakeries can use one instrument for testing all types of flours.
System Components
Fully Featured for QC, R&D, and New Product Development
The Alveolab® is simple to use, either at constant or adapted hydration (Alveo-AH optional kit). It is self-controlled with its own cooling system, automatic water injection, and automatic positioning, crushing, and blowing of dough patties.
An operator can adjust temperatures, mixing speed, air flow, relative humidity, and test timing.
This versatility allows the user to test various formulations for new recipe development and understand how the dough will perform on the production line. The data is used to determine the best flour mixture and for implementing the final production process.
The main elements of the Alveolab® are:
- Mixer bowl
- Water tank
- Resting chamber
- Test platin
- Recording system (miniPC with installed software)
Software
Alveolab® software provides straightforward, comprehensive, and intuitive data with information about tenacity, extensibility, elasticity, and baking strength. It allows the lab technician to make decisions about blends or additives. A standard analysis certificate is automatically generated for use in verifying the test results.
All traditional parameters can be obtained with the Alveolab®; additionally, the analysis data includes:
- First derivative
- Stress/Strain curve
- Possibility to record the dough consistency during mixing
- Obtain more data during testing to better predict the dough behavior and final product
